Terry ATTORN EYS Patented Jan. 8, 1952 [FRONT END MPLEMENT MOUNT rnAc'rons FOR" This invention relates to, and it is an object to provide, a novel, front end implement mount for tractors; such mount being adapted for use in connection with a push beam assembly secured to the tractor. A push beam assembly of the .type with which'the mount is adapted to be used is shown in copending application, Serial No. 726,141, filed February 3, 1947, and now Patent No. 2,485,334, issued October 18, 1949.

Another object1of the present invention is to :provide a mount, as above, which is especially adapted for use with vertically movable front 'end implements, such as the scoop here illus trated.

An additional object of the invention is toprovide a mount, as'in the preceding paragraph, which is power actuated from the tractor in a novel manner whereby to raise or lower the supported implement; the mount being adjustable, without requiring more than simple resetting of the lift mechanism associated with said mount.

At the same time, the present device is arranged so that it can also be used for the same purpose as recited in said co-pending application; the scoop-mounting assembly being removed from the main push-beam unit.

Afurther object of the invention is to provide a practical and reliable mount for front end implements on a tractor, and one which will be exceedingly efiective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the followin specification and claims.

of the combination bracket and cradle unit.

- Referring now more particularly to the char' acters of reference on the drawings, the mount is here shown in connection with a tractor l which includes a main frame 2 supported by front wheels 3 and rear wheels 4.

Push beams 5 are disposed on opposite sides of I the main frame 2 and extend longitudinally in a forward direction from pivotal connection, as at 6, with attachment plates I secured to and proiecting downwardly from the rear axle housing Hv e.seesaw-i 8 Claims. (01. 2-14140) From the pivots 6 the push beams 5 extend -'at a forward and upward incline to a point substantially directly above the front axle 8, whence said push beams are bent and extend forwardly at a downward incline to a termination ahead of the wheels 3. At their forward ends the push beams 5 include an attachment element '9 for securing said push beams to certain types of front end elements, and in this connection the arrangement is similar to that shown in the identified copending application, Serial No. 726,141. A further similarity resides in the incorporation of an upstanding cradle In to receive and guide each push beam 5. v r

The mount which comprises the essence of the present invention is arranged in association with the'push beams 5-and front axle 8 of the tractor, as follows:

On opposite sides of the tractor the axle 8 is fitted with a combination bracket and cradle unit, indicated generally at ll; such unit including a saddle l2 secured to the axle 8 by bolts [3. A bracket [4 upstands from each saddle l2 and includes a laterally outwardly projecting horizontal arm l5. This arm l5 carries a pairof transversely, spaced, upstanding bars 86 which form the cradle III for'the reception of the corresponding push beams. I

To'normally prevent upward motion of each .push beam 5, as when the described mount is in'use and vertical motion of said push beams 'isunnecessary, at least one of each pair of the upstanding bars I6 is fitted with a stop or holddown 'collar l1.

\ Ahea'd'of the corresponding cradle 10 each push beam 5 fittedwith an attachment block 18 which is normally fixed but vertically adjustable along the forwardly and downwardly inclined front end portion of said push beam.

Longitudinal lift arms H) are pivoted, at their rear ends, as at 20, to corresponding attachment blocks l8, and thence extend forwardly therefrom to pivotal connection, as at 2|, in transversely spaced relation to a front end implement, such as the scoop 22 here illustrated.

.. Each attachment block l8 includes a rigid upstanding post 23, and longitudinal control arms 24 are pivoted, at their rear ends, as at 25, to the upper end of the rigid posts 23.. At their forward ends the control arms 24 are pivoted, in transversely spaced relation, as at 26, to the scoop 22 above the pivots 2 I. v Thejlongitudinal lift arms l9 include a downwardly extending portion at their forward ends 1s.. 3 whereby to normally maintain said lift arms in substantial clearance relation to the ground.

The longitudinal lift arms l9 are connected together, in unitary relation, by a. cross bar 28.

With the above described arrangement of the longitudinal lift arms 19 and longitudinal control arms 24, it will be seen that the scoop 22 may be swung from a lowered position, as in dotted e tea mis' lpos t on. as ful lin s. n F gl, with the/scoop maintained in proper position throughout the range of its movement.

The assembly of the arms I9 and 24 is power actuated to raise or lower theimplement 22, by means of the following lift mechanism. i

Each of the combination bracket and cradle units ll includes a pair of attachment-casein;

dicated at 29 and 30, and upstanding, rearand front swing levers 3| and 32 are pivoted, at their lower ends, to said ears 29 and 30, respeotively..

rear end power mechanism (not shown) .of the tractor, which mechanismis operative at the s e. lection of the tractor driver to cause the actuat- -ing rods 33 to be shifted either rearwardly or forwardly. t V r The actuating rods 33 correspond to and are disposed directly above, the push beams 5, and said rods 33 are attached at their forward end to chains 34 which adjustably connect to the rear swing levers 34 intermediate the ndsf ofthe latter.

Other chains 35 adjustably connect between the rear swing levers 3|. at. a point, above the chains 34, and the, front swing levers 32 intermediate the ends of the latter.

Links 36 corresponding to the longitudinal lift arms 19 pivotally connect with the'cross bar 28 and the corresponding front swing levers 32 in adjustable relation to the latter.

With the above described lift mechanism it will be understood that when the actuating rods 33 are pulled rearwardly" the rear swing levers 3| "and front swing levers-32 are swung 31.66

responding direction; which pulls upwar ly the links 3K5, raising the assembly ofithe arms blocks I8 atselected positions along said portions of the push beams. When this is done the lift. mechanism is adjusted easily by reconnecting links 36 to the front swing levers 32 to an appropriate position, and by varying the lengths of "chains 34 and 3321s the setting may require.

When the use of scoop 2-2 and its highelift mounting is not requiredyan'd it is instead desired to connect an implement to cross element 9, it

I is only necessary to disconnect links 36 from cross bar 28, unclamp slide blocks H) from beams 5,

and slide said blocks oif the front end of 9id vbeams; the cross elem nt 3 b ng. mou ed 9 removable sleev s 9c normallyc urod on h beams.
